STOVE.

SPECIFICATION forming part of Letters Patent No. 453,899, dated June 9,1891.

. Application filed April 1,1890. Serial No. 346,144. (No model.)

T0 to whom it may concern:

Be it known that I, JAMES W.-CAL1A, of Castalia, in the county ofCharles Mix and State of South Dakota, have invented a new and ImprovedStove, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved stove whichis simple and durable in construction, specially designed for burningstraw, hay, trash, and rubbish as fuel, and adapted for heating andcooking purposes.

The invention also consists of certain parts and details andcombinations of the same, as will be hereinafter fully described, andthen pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of the improvement. Fig. 2 is a sectionalside eleva tion of the same on the line 2 2 of Figs. 3 and 4.. Fig. 8 isa sectional plan view of the same on the line 3 3 of Figs. 1 and 2.Fig.4 is a like view of the same on the line 41 t of Figs. 1 and 2, andFig. 5 is a perspective view of part of the front plate.

The improved stove A is provided with a shell B, preferably oval orcylindrical in shape, havinglegs B and containing an open grate 0, belowwhich is formed the ash-pit D. On the front of the grate C is arrangedan upwardly-extending and slightly-inclined plate E, having a series ofperforations or openings E, over which extend at both sides lugs Epassing downwardly, so as to prevent the fuel placed on the grate 0 fromfalling into the ash-pit D. At the same time the openings E permit ofpassing air necessary for combustion to the fuel on the grate-bars. Theplate E extends upward toward the filling-opening F, provided with theusual door, through which the fuel is introduced into the shell B, topass onto the grate O. The lower end of the front plate E of the grateis opposite the draft-door G, provided with the usual door havingopenings, through which can pass air to the interior of the shell whenthe door is closed, the said air passing under the grate C and into thechannel formed between the plate E and the shell B, so that the air canpass into one side of the fuel by passing through the openings E in thefront plate E. If desired, plates E may be arranged on all sides of thegrate C".

From the upper end of the shell B leads outwardly a short pipe H,leading to the chimney-pipe I, connected at its upper end with thechimney and having its lower end bent around, so as to form anadditional draftchannel I, which connects with the upper I part of thechimney-pipeI a suitable distance above a damper J located directlyabove the pipe H in, the chimney-pipe I. A second damper K is also heldin the chimney-pipe I a suitable distance above the entrance of thebranch pipe 1 into the pipe I, so that heat, smoke, and gases passingfrom the shell B through the pipe H can pass downwardly in pipe I, andfrom thence into the branch-pipe I, and then into the chimney-pipe I,when the damper J is closed. When the latter is open, the smoke andgases from the shell B can pass through the pipe H directlyinto theupper part of the chimney-pipe I and to the chimney. I

The damper J is solid, while the damper K is provided with the usualopenings, so that in case it is entirely closed the gases can pass atall times to the chimney. In the upper part of the shell Bis alsoarranged an oven L, passing completely through the shell and extending ashort distance on each side of the said shell. On each outer end of theoven L is arranged a door N, so that the oven can be opened on eitherside for the intro duction or removal of food to be baked or cooked. Theoven L is preferably rectangular in cross-sectionand arranged in such amanner as to have its inner walls forming channels in the upper part ofthe shell B, so that all the heat generated by the burning fuel can passaround the four sides of the said oven.

The rear channel formed between the oven and the .rear part of the shellB can be closed by a slide 0, fitted to slide on support-s P 011 theunder side of the oven, inside of the shell B, so that when the saidslide is moved rearward to close the said rear channel all the heat,gases, and smoke rising from the burning fuel passaround the front ofthe oven L, over the top before the said heat, gases, and

smoke can pass out of the pipe [I to the chimney, as previouslydescribed.

On the front end of the slide 0 is arranged a downwardly-extending lug0, adapted to be taken hold of with the poker or other instrument foropening or closing the said slide through the filling-opening F. Thefuel to be burned is passed through the filling-opening onto the grateC, and is ignited from underneath the grate-bars, through the ash-pitdoor G. The necessary air for combustion passes into the lower part ofthe shell B through the openings in the ash-pit door G, as previouslymentioned.

By arranging the front plate E in the manner previously described thepufiing of the burning fuel is completely avoided, as suffieient air ispassed to the burning fuel from underneath the grate C and also throughthe openings E in the front-plate E. By passing the outgoing heat,gases,and smoke through the branch pipe I before they are allowed topass into the chimney considerable pressure is removed from the upperpart of the shell. At the same time the draft can be convenientlyregulated by adjusting the dampers J and K in the branch pipe I in thechimneypipe I.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- In a stove, the combination, with a shellhaving a fillingopening and a draft-opening below the filling-opening,of a grate held in the shell and a perforated plate having lugsprojecting over the perforations, said plate being secured to the grateand inclined upward toward the filling-opening, but out of contact withthe shell and forming with the shell a channel, substantially as hereinshown and described.
